Twin City 电火花 and Manufacturing Inc. has been machining parts since 1959 for various industries, including defense, 航空航天, 飞机, 兽医. 然而, the company’s main focus is medical devices and components, noted Steve Lindell, vice president of the Fridley, 明尼苏达州, 商店.
“Completing difficult jobs has become our forte, especially in the medical industry,” he said. “It’s always rewarding to look back at the evolution of the company and how far we have come.”
In addition to wire and sinker 电火花ing, as well as microhole popping, Twin City 电火花 offers five-axis and other CNC milling, 激光打标, and laser welding services, Lindell补充道.
“Because we have all the different processes,” he said, “we can do just about anything.”
Lindell的父亲, 罗伯特。, started the company with a Charmilles sinker 电火花 and was one of the first to bring this technology to the Minneapolis area.
“My father is 83 and still active with the business,” Lindell说. “We still have that sinker, and he still runs it.”
然而, Twin City 电火花 is now a fully stocked Mitsubishi 电火花 facility, with 12 sinker 电火花s and 13 wire 电火花s. According to Lindell, 电火花 operators in the area are familiar with Mitsubishi 电火花s. “It’s tough finding an 电火花 operator, but the ones who come through our doors know Mitsubishi machines over any other competitor. That is part of the reason we chose Mitsubishi.”
Over the past few years, the company began to secure a number of large production orders, with some jobs having part volumes of up to 10,000甚至20,000个零件, Lindell说. “Each year it just gets to be more production-type stuff.”
To better serve customers, Twin City 电火花 determined that integrating a robot into wire 电火花 processes would be ideal for large production orders and the best investment would be a dual-wire 电火花 automation cell to pair two Mitsubishi MV1200 wire 电火花s with a FANUC six-axis robot for part handling.
Although plenty of different machine tools lend themselves to some form of automation — Lindell说 Twin City 电火花 has two robots for its sinker 电火花 side and automation for the milling machines that produce electrodes for those 电火花s — it’s rare to find a wire 电火花 with automation. That’s mainly because wire 电火花ing often creates a slug, or leftover piece from the raw material, that needs to be manually removed from the part.
Twin City 电火花 purchased the new wire 电火花s from Elk Grove Village, 伊利诺斯州-based bt365体育娱乐 Systems Inc., a subsidiary of Mitsubishi Corp., and enlisted the services of Minneapolis-based Industrial Tool Inc., an automation robotics integrator for machine tools. ITI was able to do most of the legwork at its own facility, thus eliminating any 商店 disruption for Twin City 电火花.
